Blackbox and whitebox are two testing types. The main difference between blackbox and whitebox testing is that blackbox testing checks the functionality of the system without considering the internal structure of the system while whitebox testing checks the internal structure of the system such as the program code. Black box testing and white box testing are two different types of software testing strategies, that are equally powerful, and even better when combined.

Black Box Testing Vs. White Box Testing: Key Differences

Show all documents Also to assess the feature of a software item, testing assess the quality of the product. Software testing is a process which is to be done during the development process. In other words software testing is a validation and verification process. Executing a system in order to establish gaps, errors or missing requirements in contrary to the actual desire or requirements is testing. White Box or glass box testing is the process of giving input to the system and checking how the system processes input to generate the output.

Black Box testing is the process of giving input to the system and checking the output without bothering how the output is generated. In this, the tester has little knowledge about the internal working of the software. So the testing of the output as well as the process carried out to generate the output. Software testing is a method of assessing the functionality of a software program.

And Software testing has been classified into two main categories, dynamic testing and static testing. Framework to Software Testing and Types The anticipated research approach is to use black box with the applicable combination of white box to have a hybrid which sometimes may referred as gray box which is indeed a hybrid of White box and black box.

This is a white - box approach where the authors acquired firmware images and documentation of an Engine Control Unit ECU fabricated by supplier Bosch. We then discuss how their observations can be generalised, leading to the definition of robust cleanness [25].

Any car model can be checked for being robustly clean, as described in Section 3, using hyperproperty model checking. However, this work assumes a white - box setting, too, which makes it limited in practical applicability, due to intellectual property restrictions in the automotive domain. Section 4 therefore explains how the definition of robust cleanness can be twisted to support black - box testing of real cars in connection with standardized test procedures [26]. Section 5 presents a runtime verification approach [27] to monitor how often regular trips driven in-the- wild satisfy the conditions of the RDE regulations and to check whether a trip passes the regulation.

Section 6 summarises the paper with a discussion of the greater context. There are several ways of attack detection as per our study and also prevention methods had been discussed in several research papers.

So the main motivation of our paper to penetrate the attack. One of the hacking technique is commonly occur in banking sector is sql injection. Security testing can be done by two ways i. In this paper we have shown the penetration testing of web application to detect the sql injection vulnerability.

This paper describes the penetration testing processes and mainly focuses on vulnerability discovery, attack generation and obtain the test cases and maintaining a pentester database which store all the attack responses. We have taken an internet banking transaction case study. Recent Development in Software Project Evaluation Techniques Software evaluation involves proper evaluators and appropriate selection criteria.

The emphasis should be on to how much extent are the variations in scoring by the respective evaluators and selection criteria should be based on the requirements. The risk management should be considered to alleviate the failures of software projects by using regression techniques. By qualitative weight and sum method we can obviously describe the evaluation, understand the logic behind the evaluation and knowing the possible limitations. It is feasible to design an evaluation criteria which is theoretically based for a particular purpose and goal.

The methods discussed above provides a platform for choosing relevant COTS software products which can be used in large scale systems. We have discussed about the black box and white box testing. In procedural approach to software development we have discussed about the objectives, principles and attributes and the relation among them.

This approach could be a promising effort for the evaluation of software project methodologies. Survey of Software Testing Techniques Abstract: Software created will never be perfect without being tested and approved.

This makes us to find a way for testing hidden bugs at different levels by a good technique. Testing is a process where we can spot hidden bugs, code errors or any unused code in a given software. Currently there are many techniques being used for testing errors in software, among them most practiced techniques for testing a software are black box testing , white box testing and grey box testing.

In this paper we are comparing about various software testing techniques to find out their effectiveness in generating test cases and enhancing the quality of the software system.

Software Test Process, Testing Types and Techniques The main quality factor in software is to meet its required functionality and behavior.

The functional part of software includes the external behavior that mainly specifies all user requirements. The high level design of the software is produced so that the customer would be satisfied at an early stage of design and development.

The functional testing revolves around the basic work flows and alternative flows of software. These flows can be represented by various use case diagrams like sequential diagrams, class diagrams, component diagrams etc [9][10].

Automated Test cases are also generated by UML models [8]. There are different types of functional testing methods and techniques [18] which could be performed at various levels of testing i. There are lots of testing performed at various levels of testing like black box testing [19], white box testing , grey box testing [21] regression testing [22][24], fuzz testing , use case testing , exploratory testing , smoke testing [25], sanity testing [26], acceptance testing [27], alpha, beta testing etc.

Test cases are built around specifications and requirements i. Testing refers to the process of evaluating attributes like correctness, completeness, security, consistency, unambiguousness, quality etc. Testing is an activity to find the bugs in software that may perform by tester or by applying strategies like white box or black box. So, the activities involved in the testing should be in planned way. Investigation onto the Software Testing Techniques and Tools: An Evaluation and Comparative Analysis The basic software testing techniques are Dynamic white box , black box and grey box and Static Inspection, walkthrough, technical and informal reviews with each having its unique attribute and functionality [5, 22].

Dynamic testing is an automated testing technique which is executed by a professional for proper analysis of the software dynamic relationship behavior.

While Static techniques require no code and it is performed prior to code deployment for accurate code evaluation by a non-professional. Similarly, the testing tools are broadly categorized into Manual and Automated tools. While Manual testing tools are executed manually by the developers with the use of a test plan, an automated testing tools is said to overcome the manual challenges.

Hence, the exponential rise in the number of companies embracing and developing automated testing tools for series of applications. This research work is aimed at investigating onto some popular software techniques black , white and grey box and automated tools test complete, Selenium, JMeter and Hpload runner and as well to carried out a comparative and evaluation analysis of both.

An Efficient Method for Automatic Generation of Linearly Independent Paths in White-box Testing However, automatic and highly efficient generation of linearly independent paths from source codes in basis path testing is still lack. To solve the problem, this paper proposes a new and efficient method of path-based tests after analyzing open literature in this area. Through adding an edge to the program Control Flow Graph CFG , basic path testing problem is transformed to find all strongly connected components and circuits in graph theory.

We propose Automatic Basis Path Construction ABPC algorithm by reducing fruitless searching to improve time complexity and efficiency of basic path generating.

Also scalability is showed in proposed method. As these applications are meant to be used with multiple users at the same time, race conditions between updates to the same data are likely to occur and can result in diminished user experience.

That is why they set out to cre- ate a black - box visual analysis tool that first learns potential behaviour from recorded user interactions and then replays these sequences to find conflicts automatically. They could successfully find several functional issues in col- laborative web applications.

The approach seems similar to what Mutlu et al. This test method is also comparable to how Adamsen et al. Development, testing and reporting of mobile apps for psycho social interventions: lessons from the pharmaceuticals Once the app is feature complete, the beta testing is carried out. This can reveal unknown defects or bugs.

This is normally tests usability or acceptability of the app. A Progressive Testing Solution with Spiral Process Model to Develop Erp Software in Pakistan The revolutionary spiral process model is designed to provide an effective way to overcome all of the problems faced by all of these approaches.

Agile is not concerned with testing and documentation of the product development process. Water fall model focuses on the document, but does not pay attention to the testing phase. In the water fall model, the testing phase becomes too late, and because of this problem, these models become risky because the product may fail after consuming effort and resources.

The spiral process model is a custom and iterative, incremental model. Because of these characteristics, it has become a good choice for enterprise resource planning software development in Pakistan.

In the revolutionary spiral process model, the latest testing strategies are being introduced to make traditional spiral process models more efficient by increasing customer engagement, and understandable documentation developed for the maintenance phase, and by using extreme testing techniques such as acceptance Test-driven development and pair programming.

It is necessary to collect the customer's real requirements during the planning phase. The spiral process model for improving this capability innovation uses acceptance test-driven development ATDD techniques. Stress testing also determines the behavior of the system as user base increases.

In stress testing the application is tested against heavy loads such as large no. Black-box testing of practical movie recommendation systems: a comparative study In this work, we have investigated what kinds of recommendation schemes have been ex- ploited in the practical recommendation services.

As a conclusion, this paper has evalu- ated user modeling process in several practical recommendation systems. Black - box test- ing scheme has been applied by comparing recommendation results. User models i. Improving the Performance of Database Applications by using Black Box Regression Testing In [1], Regression testing , involved during the development of the software, where it plays the important role. Initially it checks the checks the test suite.

Where test suite consists of the number of test cases with in the test suite. It checks for the absolute test cases and then perform the regression test selection then perform the augmentation of test cases and minimizes the number of the test cases inside the experiment lastly organizes the test suite for the advancement of the test cases. So regression plays an important role in the development of the software. Faults will be found by everybody using the software.

Testing is a quality control measure used to verify that a product works as desired [10]. Software testing provides a status report of the actual product in comparison to product requirements written and implicit.

Testing should reveal as many errors as possible in the software under test, check whether it meets its requirements and also bring it to an acceptable level.

A White Box Testing Technique in Software Testing : Basis Path Testing Software Testing is the emerging and important field of IT industry because without the concept of software testing , there is no quality software which is produced in the industry. Verification and Validation are the two basic building blocks of software testing process. There are various testing tactics, strategies and methodologies to test the software.

Black Box testing is the process of giving input to the system and checking the output without bothering how the output is generated.

White-box testing also known as clear box testing , glass box testing , transparent box testing , and structural testing is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality i. In white-box testing an internal perspective of the system, as well as programming skills, are used to design test cases. The tester chooses inputs to exercise paths through the code and determine the expected outputs. This is analogous to testing nodes in a circuit, e. White-box testing can be applied at the unit , integration and system levels of the software testing process.


Abstract and Figures. Since the mid s, software testing has been dominated by two major paradigms, known as black box testing and white box testing. Strategies for black box testing are based on the specification of the software component under test. Principles of Boundary Value Testing.


Black Box Testing

In Black-box testing, a tester doesn't have any information about the internal working of the software system. Black box testing is a high level of testing that focuses on the behavior of the software. It involves testing from an external or end-user perspective.
